It all depends on what you want to do. Usually, we try to avoid sharing buffers read/write between multiple process, it makes debugging much harder - especially buffer leaks or use-after-free... Here is an example to share VPP buffers read-only with snort so that snort can inspect traffic and gives a verdict back without any copy: https://git.fd.io/vpp/tree/src/plugins/snort
